The green technology is the technology for the green society having the green safety. The green technology is not only save the resource and recycle the resource but also save the energy and recycling the energy. The core technology of the Green Technology is the 7Less Microsystems. The 7Less Microsystems are the Xtaless Clock Generator, the Resistorless Current Sensor, the Capacitorless Low Drop Voltage Regulator, the Inductorless Switch Mode Power Supply, and the Avalanche Diodeless True Random Noise Generator, the Sawless Low Noise Amplifier, and the Brakeless Hybrid Electrical Vehicle. The Gain-Boost-Q LC VCO is the fundamental technology of the Xtaless Clock Generator, Spurfree/Jitterless Frequency and Phase Lock Loop, multi-phase high-speed high frequency clock and the Sawless Low Noise Amplifier. The switch inductor is the fundamental technology of the high power efficiency of the Switch Mode Power Supply. The high efficiency converter technology is the fundamental of the high efficiency power amplifier. The residue energy is recycling in the system to save the power from the wasted dissipation. The high efficiency power amplifier is the fundamental technology of the high efficiency plasma light and the 4.sup.th generation OFDM Ultra-Wide Band communication and cellular phone. The dynamic balanced battery is the fundamental technology of the Hybrid Electric Vehicle. The polarized camera with the polarized micro lens and polarized cellular phone with the polarized antenna make the signal transmission much more clearly. All the above green technologies constitute the essential characteristics technologies of the Green Society.
